Report Control Method and Apparatus, Device, Medium, and Computer Program Product

1. A report control method, comprising: transmitting, by a session management function (SMF), in response to a determination that a report rate of an edge application server discovery function (EASDF) reaches a limiting threshold, a stop instruction to the EASDF, as a defense against a denial of service (DOS) attack or distributed DOS (DDOS) attack, the stop instruction being used for instructing the EASDF to stop transmission of a report to the SMF by the EASDF, wherein the report is a report transmitted by the EASDF triggered by a behavior of a user equipment (UE), and the report includes at least one of a domain name system (DNS) query triggered report or a DNS response triggered report.

2. The method according to claim 1, further comprising: transmitting, by the SMF, a configuration rule to the EASDF, the configuration rule comprising a forwarding rule but no reporting rule, and the reporting rule being a rule for triggering the EASDF to transmit the report.

3. The method according to claim 1, further comprising: configuring, by the SMF, the limiting threshold for the EASDF, the limiting threshold being used for configuring an upper limit of a report rate of the report for the EASDF.

4. The method according to claim 1, wherein the stop instruction includes back off time, the back off time being time when the EASDF stops transmission of the report.

5. The method according to claim 1, further comprising: transmitting, by the SMF, a start instruction to the EASDF, the start instruction being used for instructing the EASDF to resume transmission of the report.

6. The method according to claim 5, wherein the start instruction includes a shared start instruction, the shared start instruction being a start instruction shared by at least two types of reports of the EASDF; or, the start instruction includes at least one of a first start instruction and a second start instruction, the first start instruction being a start instruction corresponding to a first-type report of the EASDF, and the second start instruction being a start instruction corresponding to a second-type report of the EASDF.

7. The method according to claim 5, wherein the back off time includes shared back off time, the shared back off time being back off time shared by at least two types of reports of the EASDF; or, the back off time includes one or both of first back off time and second back off time, the first back off time being back off time corresponding to a first-type report of the EASDF, and the second back off time being back off time corresponding to a second-type report of the EASDF.

8. The method according to claim 1, wherein the limiting threshold includes a shared threshold, the shared threshold being a threshold shared by at least two types of reports of the EASDF; or, the limiting threshold includes one or both of a first threshold and a second threshold, the first threshold being a threshold corresponding to a first-type report of the EASDF, and the second threshold being a threshold corresponding to a second-type report of the EASDF.

9. The method according to claim 1, wherein the stop instruction includes a shared stop instruction, the shared stop instruction being a stop instruction shared by at least two types of reports of the EASDF; or, the stop instruction includes at least one of a first stop instruction and a second stop instruction, the first stop instruction being a stop instruction corresponding to a first-type report of the EASDF, and the second stop instruction being a stop instruction corresponding to a second-type report of the EASDF.

10. A report control apparatus, comprising: a memory storing computer program instructions; and a processor coupled to the memory and configured to execute the computer program instructions and perform: transmitting, by a session management function (SMF), in response to a determination that a report rate of an edge application server discovery function (EASDF) reaches a limiting threshold, a stop instruction to the EASDF, as a defense against a denial of service (DOS) attack or distributed DOS (DDOS) attack, the stop instruction being used for instructing the EASDF to stop transmission of a report to the SMF by the EASDF, wherein the report is a report transmitted by the EASDF triggered by a behavior of a user equipment (UE), and the report includes at least one of a domain name system (DNS) query triggered report or a DNS response triggered report.

11. The apparatus according to claim 10, wherein the processor is further configured to perform: transmitting, by the SMF, a configuration rule to the EASDF, the configuration rule comprising a forwarding rule but no reporting rule, and the reporting rule being a rule for triggering the EASDF to transmit the report.

12. The apparatus according to claim 10, wherein the processor is further configured to perform: configuring, by the SMF, the limiting threshold for the EASDF, the limiting threshold being used for configuring an upper limit of a report rate of the report for the EASDF.

13. The apparatus according to claim 10, wherein the stop instruction includes back off time, the back off time being time when the EASDF stops transmission of the report.

14. The apparatus according to claim 10, wherein the processor is further configured to execute the computer program instructions and perform: transmitting, by the SMF, a start instruction to the EASDF, the start instruction being used for instructing the EASDF to resume transmission of the report.

15. The apparatus according to claim 14, wherein the start instruction includes a shared start instruction, the shared start instruction being a start instruction shared by at least two types of reports of the EASDF; or, the start instruction includes at least one of a first start instruction and a second start instruction, the first start instruction being a start instruction corresponding to a first-type report of the EASDF, and the second start instruction being a start instruction corresponding to a second-type report of the EASDF.

16. The apparatus according to claim 10, wherein the limiting threshold includes a shared threshold, the shared threshold being a threshold shared by at least two types of reports of the EASDF; or, the limiting threshold includes one or both of a first threshold and a second threshold, the first threshold being a threshold corresponding to a first-type report of the EASDF, and the second threshold being a threshold corresponding to a second-type report of the EASDF.
